It's easy to be cynical about celebrities and their photo-op charity work, but it's hard to doubt actress Anita Yuen Wing-yee's sincerity with the Lotus Light Charity Society. As ambassador, she's made three trips bringing help to poor villages in Gansu province. The latest visit is documented on a TVB Jade programme airing at 11pm on the next two Saturdays. At a press conference on Thursday afternoon, Yuen broke down when she was surprised with a personal thank-you letter from a nine-year-old Gansu girl she had met previously.

'Auntie Yuen, are you living happily?' the letter, read by a local student, began. 'I miss you a lot. I am very happy wearing the clothes and using the school bag that you gave me.' The note then explained how the orphan's aunt and uncle had to leave the village to find work, leaving her to care for her sick and elderly grandparents. 'My life is very tough. Auntie Yuen, I miss you so much,' it concluded.

Yuen couldn't hold back her tears. 'There are children in Hong Kong who try to talk their parents into letting them skip school or tutorial classes, while these Gansu kids want to go to school so bad but they can't because they have to take care of their family. It's so unfair,' Yuen said while trying to compose herself. Judging by her emotional state, this wasn't a performance.

As part of the media event, singer Fiona Sit Hoi-kei announced she had designed two T-shirts to be sold at shops Ztampz, Bread & Butter and Ginger Bread specifically for the charity.
